-- =============================================================================
-- Fix: PGRST205 "Could not find the table 'public.simulation_runs' in the schema cache"
-- =============================================================================
-- 1. Open Supabase Dashboard → your project → SQL Editor → New query.
-- 2. Paste and run this entire script.
-- 3. If the API still errors after ~1 minute, run the last line alone to reload PostgREST.
-- 4. Create Storage bucket "reports" (private) under Storage if you use report files.
-- =============================================================================

create table if not exists public.simulation_runs (
  id uuid primary key,

  report_storage_path text,

create index if not exists simulation_runs_user_id_idx on public.simulation_runs (user_id);
create index if not exists simulation_runs_status_idx on public.simulation_runs (status);

-- If the table exists but REST still returns PGRST205, wait ~1 min or pause/resume the project
-- in Dashboard → Settings. (Uncomment below only if your project supports it.)
